Brushless Electric Motors from the Market Leader of Propulsion Systems for Drones/UAVs

T-Motor offers Electric Motors of the highest Quality and Industrial Grade.
First Class Efficiency and Reliability are the Result of excellent Processing and Components. Manufacturers of UAVs for industrial operations can hardly do without the brand T-Motor.

 

Efficiency increase by 15%+.

  • 14 Patents
  • Match with ultra-light props
  • Sine wave features
  • FOC ESC
  • Silver winding

 

Flight time 5% longer

 

Imported Custom Silver Wires

Fast current flow on silver wires surface improves motor response speed for easy control over aircraft. Silver winding greatly reduces copper loss and helps lower motor heat by 30%.

 

Magnetic Circuit Optimization

Curved magnets in new U8 are with less magnet space.

Optimized design help save energy during flight.

 

Max. Thrust: 7.3kg - Heavy Load

With the fall of motor temperature, the max. thrust of new U8 reaches 7.3kg from 5kg which doubles the aircraft payload.

 

A max. of 34°C temperature fall can be achieved

* Data obtained at 32V+500W motor running 10mins

 

Motor Protection - Safe flight - Patent Technology

Protect motors from sand, dust, foreign matters and magnetic particles.

Bore Diameter of net < 1mm

  • Foreign Matter

 

Silicon Steel Sheet

Special anti-rust treatment

Capability of passing 48h salt spray test

 

Service Life

1500 flights are out of question (40mins/flight)

 

Imported Custom Bearings, Dual Bearing Protection

Simulated analyses are carried out based on the stress under operating condition in axial and radial directions. Redesign of custom bearing contributes to prolong the bearing life to 1000h+ under normal operation.

Property of anti-rust and anti-corrosion from dual bearing protection gets the motor through 6h salt spray test.

 

N45 UH Magnet Grade

High grade magnets ensure high efficiency in high temperature.

 

Safety

The silver wire lead avoid soldering. Say no to faulty and cold soldering.

Imported German 7075 aviation Aluminium alloy reinforces the motor structure by 20%.

 

Silver lead the trend with intelligence

FOC ESC: Smooth control, Low noise, High efficiency.

Latest ultra-light 28"carbon fiber prop weighs only 55g (weight of standard 28"CF prop is 98g).

An increase of 12% to flight time and weight loss of 320g (quadcopter) is attainable once U8LITE and the ultra-light prop are on your aircraft.

  • Sine Wave Driving
  • FOC ESC
  • Ultra-light Prop

 

No prop adapter is required with 20g weight reduction: Easy Installation

Tip: Do not forget the 2g location pin during installation!
